In this section, you can add and remove cluster members while also changing the priority of an ADC in the cluster. The section consists of two panels and a set of arrow keys in between. The area on the left is the Unclaimed Devices, while the rightmost area is the Cluster itself.
Adding an ADC to the cluster
Before adding the ADC to the cluster, you must ensure that all the ADC appliances have been provided with a unique name set in the System > Network section.
You should see the ADC as Priority 1 with Status green and its name under the Cluster Members column in the management section. This ADC is the default primary appliance.
All the other available ADC’s will show up in the Unclaimed Devices window within the management section. An Unclaimed Device is the ADC that has been assigned in the Cluster Role but has no Virtual Services configured.
Highlight the ADC from the Unclaimed Devices window and click the right arrow button.
You will now see the following message:
Click OK to promote the ADC to the cluster.
Your ADC should now be showing as Priority 2 in the cluster members list.
Manually adding an ADC to the cluster
In systems where Broadcast is blocked, you will need to choose Unicast or Hybrid mode in order to add an ADC to the cluster.
To add an ADC manually to the cluster:
1. Provide its IP address
2. Provide the Machine Name – this is available in the System > Networking section.
3. Click Add Server
The ADC will then be added to the cluster.
If the ADC you are trying to add is already in a cluster, you will be notified via an error message.
Removing a cluster member
Highlight the Cluster Member you wish to remove from the cluster.
Click the left arrow button.
You will be presented with a confirmation request.
Click OK to confirm.
Your ADC will be removed and be shown on the Unclaimed Devices side.
Changing the priority of an ADC
There may be times when you wish to change the priority of an ADC within the members' list.
The ADC at the top of the Cluster Members list is given Priority 1 and is the Active ADC for all Virtual Services
The ADC that is second in the list is given Priority 2 and is the Passive ADC for all Virtual Services
To change which the ADC is Active simply highlight the ADC and click the up arrow until it is at the top of the list
